摘要

研究了离心复合铸造工艺和复合变质处理对高速钢辊环性能的影响，结果表明，选用变质高碳无钴高速钢作外层，用球铁作内层，选择合适的离心机转速、两种金属熔液浇注间隔时间和浇注温度，结合采用表面感应热处理工艺，可获得硬度高、均匀性好、内外层结合良好的高速钢复合辊环，用于工业生产其使用寿命比高铬铸铁辊环提高５倍以上。

Abstract

The effect of compound casting technology and compound modification on the properties of high Speed steel roll collar was studied.The results showed that compound high speed steel roll collar with high and even hardness and good bond between outer and inner layers could be gained when the modified colbalt free high speed steel in outer layer and nodular iron inner layer in connection with appropriate rotational speed of centrifugal machine

pertinent pouring interval between two kinds of the melt and moderate pouring temperature as well as surface induction heat treatment were chosen.It is indicated in industrial use that the service life of compound roll collar is higher by 5 times than that of high chromium cast iron collar.
